To all Lo/0m it may concern.'

Be itknown that I, CYRUS S. RADFonD; a citizen of the United States, and resident ot' the city and county of Philadelphia, State of Pennsylvania. have invented an Improvement in Lock Mechanism; of which the following is ar speciiication. Y

It is one of the objects of my invention to provide a simple and efficient mechanism to enable a lock to be operated by a key insorted through the knob of a door or drawer. For this purpose I employ a tubular sleeve which is inserted through the lock casing and knob. and contains a key actuated part, adapted to be operated by a key inserted through the knob and sleeve, and to contro-l the operation of the lock-bolt. This sleeve with its key-actuated part may be readily applied to ordinary locks. The portion ot' the sleeve which extends through the lock casing is slotted, and the key actuated part within the sleeve operates the devices for actuating t-he bolt or controlling its operation through this slot.

the door or drawer to form a bearing for the knob and mounting the knob loosely upon it, I enable the knob to be used to actuate a spring latch.

In the drawings; Figure 1 is a front elevation of a lock embodying the invention and showing the same applied to an ordinary handle or knob; Fig. 2 1s a front ele-` vation of the same with the face plate of the lock casing and handle removed and the spindle-socket in vertical section; Fig. 3 is a vertical section on the line A-A of Fig. 1; Fig. 4 is a plan view of the key; Fig. 5 is a front elevation similar to Fig. 2 but showing the invention applied to a spring latch and its .actuating knob; Fig. 6 is a vertical sectional view oit the lock and latch on the line B-B of that figure but including the face plate and latch actuating knob; Fig. 7 is an elevation similar to Fig. 2 but showing a modification; Fig. S is a vertical section of the lock shown in Fig. 7 on the line C-C ot' that figure but including the face plate and knob; Fig. 9 is a plan view with part in section of the key foi-actuating the lock shown in Figs. 7 and 8; Fig. 10 is a front elevation similar to Fig. 7 but showing the modified form of locking mechanism of Figs. 7 and 8 applied to a springl latch; Fig. 11 is a vertical sectional view ot By extending the- I front end of the sleeve beyond the face ot the modification shown in Fig. 10 on the line D-D of that figure but showing the same with knobs adapted to be `actuated from either side; Fig. 12 is a longitudinal section of the knob, sleeve and spindle with an additional key socket; Fig. 13 is a transverse section of the same on the line E-E of Fig. 12; and Figs. 14, 15 and 16 are front elevations similar to Figs.. 2, 5, 7 and 10 illustrating further modifications.

o is the lock-case which contains the bolt, latch and actuating mechanism and is adapted to be secured to the frame of a door, lid or drawer in the usual manner. I shall first describe the construction shown in Figs. 1 3, in which the lock has an ordinary bolt Z9 and is applied to a door or drawer provided with a knob or handle c. The bolt is actuated by the bit d of a key-pin e, which is journaled in a sleeve f extending through the knob and lock-casing. This sleeve. f is cut away or slotted at the lower portion of the inner end as at f and projects through slots in the face plate a and case a. It is secured in place by a nut f2 on its threaded extremity. The key-pin e is journaled at its rear-end in the case o and the bit CZ projects through the slot f into actuating engagement with the bolt Z1. The front end of the key-pin is suitably notched as at e to engage the end of a key c/ inserted through the sleeve in the knob. The key-pin may thus be actuated by the key g to operate the bolt, the slot f in the sleeve f being sufficiently wide for the purpose, preferably 900. In this construction an ordinary knob or handle is em ployed, but in Figs. 5 and 6 I have shown the knob arranged for actuating a spring-catch 7L which is operated by a pin 7L on the knob extending through a slot in the face plate and engaging a slot in the catch. In both of these forms the key g engages directly with the key-pin e which actuates the bolt, but in the forms shown in Figs. 7-11 I employ intermediate devices-preferably gears`for transmitting motion from the key to the key-pin and its bit.

t' is a short spindle journaled in the lock case a and projecting atI the front through the face plate a into the tubular knob c. This spindle is arranged within the tubular sleeve 7', and carries a small pinion y', the teeth of which engage the teeth of a small segmental gear 7c on the key-pin e, which is journaled on the lock case immediately below the spindle fi, so that the teeth ot the pinion and gear will engage tlnfough the slot f in the sleeve fmJ fm, are small springs secured to the gear f and embracing the outside of the sleeve 1 ttor the purpose ot' preventing the key-pin turning so tar as to entirely disengage the teeth ot tbe gear from the pinion The spindle `2' may be operated by a suitable key g (Fig. 9) .inserted through the knob c and having a socket g2 to engage the head ot the spindle. In the form shown in Fig. 8 the knob c is integral with the sleeve f. This Aform is particularly adapted for small metal knobs, and the spindle i permits a very small key to be used.

In Figs. l0 and 1l the construction is shown applied to a double knob adapted. to be operated :from either side and also connected with a spring latch. In this form the outer end of the sleeve f is connected with a second sleeve f3 on which the knob c is mounted and the rear end ot the spindle z' is extended tlnrnlgh the lock casing into this sleeve f as shown at if", The two knobs are connected by a pin 71.2 which actuates the spring catch it in. the usual manner.

In all of the forms shown the key insorted through the knob engages directly with the key-pin or spindle Ii. This does not permit of much variation in the keys. It desired, however, a set ot tumblers or an auxiliary key sleeve may be employed in the sleeve j', through which the key must pass to opera-te the key-pin or spindle t'. Such construction is shown in Figs. 12 and 13, in which n is a rotary sleeve in the sleeve j" in front oit the spindle i, having an irregular passageway a through which the key must pass before its end can engage the spindle.

In each oit the forms shown in Figs. 1-11 the key-pin actuates a simple bolt and may be applied to an ordinary lock. In the construction shown in Fig. 14, however, a special locking bolt and actuating devices are employed. I he spindle z' is provided with the pinion y', as in the 'forms shown in Figs. 7-11, but it engages a segmental gear 7a on a plate o pivoted in the lock case and having a cam slot 7? which engages a pin p on the bolt 7). When the spindle i is turned by its ke v the plate 0 will be rocked by the gears j and 1 and the bolt b will be projected or retracted b v the action ot' the cam slot p on the pin 77.

In the terms shown in Figs. 15 and 1G, the key-pin c and its bit d act as a lock for a bolt L2, which is provided with a shoulder or ottset a engaged by the bit CZ. IWhen the key-pin is operated to move its bit ont ot enpaigement with the shoulder s the boltb2 may be moved. In the form shown in Fig. l5 the bolt is projected by a spring t and is retracted by a pin 7L3 on the knob engaging the bolt.; in the form shown in Fig. 1G the bolt is both projected and retracted by a pin h" on the knob working between lugs h5 on the bolt.

In the forms shown in Fi Yl-ll and It the bolt I) or L is actuated positively by power transmitting connections between the key-pin e or spindle i, while in the forms shown in Figs. 15 and 1G the bit (Z acts as a locking device to hold the boltl 7f3 against movement until the bit is raised; in either case, however, the bit CZ and its connections constitute motion controlling connections between a key actuated parteither the key pin c or the spindle l#-and the lock-bolt, by which the unlocking ot the bolt is controlled by the operation of the key actuated partoperated by a key inserted through the knob and. sleeve.

lVhile I have shown the key bit (l in Figs. 2, 5, 7 and l() acting directly on a lock bolt it is apparent that it may operate through tuinblers in the manner usual in ordinary tumbler locks. rlhe bit d is similar to the bit oit an ordinary key and may operate the lock-bolt in the same manner that an ordinary key operates, either directly or through tumblers or other connecting mechanism.

`What I claim is as follows:

l. In a lock mechanism, the combination with a lock casing and a drawer or door knob, ot a tubular sleeve carried by the knob, projecting at its inner end through the back plate of the casing and provided with a slot, means to secure the projecting` inner end of the sleeve against withdrawal through the back plate of the casing, a key actuated part in the sleeve, a lock-bolt, and motion controlling connections between the bolt and key actuated part working through the slotted portion ot the sleeve.

2. In a lock mechanism, the combination with a lock casing and a drawer or door knob7 ot a tubular sleeve carried by the knob, projecting at its inner end through the, back plate of the casing and provided with a slot, a nut on the j irojecting end ot said sleeve to secure it against withdrawal through the back-plate, a key actuated part in the sleeve, a lock-bolt, and. motion controlling connections between the bolt and key actuated part working through the slotted portion of the sleeve.

3. In a lock mechanism, the combination with a lock casing and a drawer or door knob, the back plate of said casing being provided with a. slot in line with the knob, a tubular sleeve having its outer end slotted extending through the knob and casing with the extremity of the slotted end projecting through the slot in the back plate ol the casing, a key actuated part in said sleeve adapted to be operated by a key inserted through the knob7 a lock-bolt, and motion controlling connections between the bolt and key actuated part working through the slotted portion of the sleeve.

il. In a lock mechanism, the combination with a lock casing, of a tubular sleeve eX- tending entirely through the casing, a knob loosely mounted on said sleeve, a key actuated part within the sleeve journaled in the back plate of the casing and adapted to be operated by a key inserted through the knob and sleeve, a lock-bolt within the casing, power transmitting connections between the key actuated part and bolt, a latch, and operating connections between the knob and latch.

5. In a lock mechanism, the combination with a lock-casing, of a tubular sleeve eX- tending entirely through said casing and having a slotted portion, a rotary spindle in said sleeve adapted to be operated by a key inserted through said sleeve, a pinion carried by said spindle and working through the slotted portion of the sleeve, a lock-bolt in said casing, and power transmitting connections between said bolt and pinion.

6. The tubular sleeve f adapted to be inserted in a lock casing and having the slot f, in combination with a rotary key actuated part journaled in said sleeve and provided with motion controlling means 0perating through said slot f in the sleeve for controlling a lock, a knob loosely mounted on said sleeve in front of the lock casing, a. spring latch, and a connection between said knob and latch.

In testimony of which invention, I have hereunto set my hand.
